WARMING-PAD.

SPECIFICATION forming part of Letters Patent No. 640,534, dated January2, 1900.

Application filed October 1, 1898.

To aZZ whom it may concern:

Be it known that I, LYMAN OHENEY,-a citizen of the United States,residing at Nashua, in the county of Hillsborough and State of NewHampshire, have invented certain new and useful Improvements infarming-Pads; and Ido hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to warming-pads for medicinal purposes for therelief of pain, and it Will also be found useful in warming the feet andother parts of the body which have become chilled, and being composedinteriorly of soapstone in a dry powdered state, which, being a poorconductor of heat, will retain the' heat for a considerable length oftime and be free from the objections occasioned by the use of hot-waterbags.

The invention consists of a suitable soft covering or casing which isfilled with soapstone in a powdered or pulverized form,which pulverizedmaterial is held in the desired shape or position by forming the outercasing with pockets which prevent the pulverized material from settlingin one corner or end of the casing and secures a flexible pad of uniformthickness and shape throughout, which can be laid on the affiicted partor wrapped around the same very conveniently and sat isfactorily.

In the accompanying drawings, Figure 1 is a perspective View of a padmade in accordance with my invention.- Fig. 2 is a vertical longitudinalsection through thesame, and Fig. 3 is a perspective view of a casing inwhich the pad is shipped and which is used on a stove or other place inheating the same.

A in the drawings represents the casing for the pad,whichis made,preferably, of soft material cut into a suitable shape, and consists,preferably, of an upper and lower piece ov a, which are sewed togetheron three sides near their edges and as at a a a and longitudinally atintervals, as at a or, so as to form independent pockets a The pocketsare then filled from the open end of the pad and the pad then sewed, asat of, which closes the ends of the pockets and also completes thesewing entirely around the pad. By this Serial No. 692,480. (No model.)

construction and arrangement a fiat pad is secured with a series ofindependent pocketsdesirable size, so that it can be applied around thepart of the body as well as applied to it, which could not be readilydone if solid blocks were employed.

It will be observed from the aforegoing de scription that the outercasing or covering is finished andthe pockets formed before theheat-retaining material in a dried powdered form is placed in theindependent and completely-separated pockets, by which construction andarrangement the material in the pockets is not only kept separate, but aflat pad is produced which is pliable throughout and can be readily andconveniently applied to and around the afflicted part, which could notbe done if the soapstone were in the form of blocks or in any othercondition other than in a dry pulverized state and arranged inindependent pockets, the material remaining in a dried pulverizedcondition at all times. If the filling material were moistened or soakedwith medicinal liquids, it would destroy the article as a warming-pad.

In Fig. 3 I have shown a device in which the pad is shipped and whichwill be found very convenient in heating the same. This device consistsof a frame B, having downwardly-turned edges 1) b and a top covering ofwire-gauze 19, between which is a lining of asbestos. If the heat isvery great with which the pad is heated, the holder is placed on astoveor other heater in the position shown in the drawings; but if the heatis not very great, the holder is inverted during the heating operation.In either arrangement the pad will be prevented from coming in directcontact with the heater.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A warming-pad for medicinal purposes,

comprising in its construction asuitable soft In testimony whereof Ihereunto affix my covering which is formed with a plurality of signaturein presence of two witnesses. independent pockets, which are filled withT T v T 7' soapstone in a dry powdered state, the Whole L1 MAL OHEL 5pad being fiat and flexible throughout so that Vitnesses:

it can be conveniently applied to or around R. T. SMITH,

the afflicted part, substantially as described. l O. D. PARKER.
